The condition of the drive belt should be checked annually,
or after every 25 hours of operation. If the belt is cracked,
worn, frayed, or stretched, replace it. Only replace it with
the original banded belt type, do not use singe belt types.
To replace the belt:
1. Remove idler pulley. The pulley is removed by loosening
the 1/2” mounting hardware.
2. Lift belt idler pulley off of the idler arm weldment.
3. Remove the drive belt from the pulleys and take the old
belt out of the machine.
4. Install new belt on pulleys and lower belt idler. Check
alignment of pulleys and adjust if needed.
5. Reinstall the belt idler pulley to the idler arm weldment
using the 1/2” hardware. Tighten bolt to proper torque.
5. Check belt tension before start-up. If necessary adjust
spring tension
